Sadler 32 rudder bearings

Hi ,

my sadler 32 rudder is really stiff. There’s no play just stuff to move . I bought the boat in October last year and thought it might ease up with use. I’m thinking to have the boat lifted out the water and remove the rudder to see what’s going on.

Does anyone know where you can buy replacement bearings ? Just in case did like to have some there in case they are knackered !
